The difference in electronegativity between two elements bonded into a compound by ionic bonds is almost always greater than the difference in electronegativity between two elements bonded into a compound by covalent bonds.

What values best classifies a bond between 2 atoms as being covalent?
An electronegativity difference of less that 1.7 between the atoms
What type of electronegativity difference exists between atoms in a covalent bond?
If the electronegativity difference between two atoms is less than 1.7, then a covalent bond is formed between the two atoms.
How is electronegativity used to determine bond types?
If the electronegativity difference is less than 2, then covalent bonds are formed. If the electronegativity difference is greater than 2, then ionic bonds are formed.
Is mgO a covalent bond?
No. It is ionic because the electronegativity difference is greater than 1.7 (2.3).
Is N-O ionic or covalent?
Definitely covalent. The electronegativity difference isn't great enough for a bond between Nitrogen and Oxygen to be ionic. In order for a bond to be Ionic, the electronegativity difference must be 2.7 or greater. The electronegativity difference of N and O is merely .4. Not even close! The further apart on the periodic table two elements are, the greater the electronegativity difference. Electronegativity GENERALLY increases going up and to the right on the table. There are, however, some cases in which exceptions can be noted, but they are not too common.

The greater the electronegativity difference between two bonded atoms the greater the percentage of?
The greater the electronegativity difference between the two bonded atoms, greater is the ionic character of the bond.
What covalent bonds are most polar?
Bonds between two nonmetals that differ in electronegativity (EN) are usually polar. Electronegativity is the tendency of an atom to attract electrons. Nonmetals with EN differences of 0.5-1.6 form polar covalent bonds. The greater the difference, the more polar. If the EN difference is
Why hydrogen chloride is a covalent compound but sodium chloride is an ionic compound?
Covalent bonds are formed when the electronegativity difference between the two atoms is less than 1.7. Ionic bond is formed between two atoms having electronegativity difference of 1.7 or above. The electronegativity of hydrogen is 2.1 and that of chlorine is 3.0. So in HCl the electronegativity difference is 3.0-2.1=0.9 which is less than 1.7. Therefore they will form a covalent compound. Electronegativity of Sodium is 0.9 and that of chlorine is 3.0. So the electronegativity difference is 3.0-0.9=2.1 that is greater than 1.7 and will form an ionic bond and hence it will be an ionic bond.
Is MgO a polar covalent bond?
No. It is ionic because the electronegativity difference is greater than 1.7 (2.3).
Does covalent compounds have a high or low electronegativity?
In comparison with ionic bonds, the difference in electronegativities of elements in a covalent bond have a lower difference in electronegativities. A covalent bond occurs between two nonmetals that have a difference in electronegativities that is 1.7 or less. Usually an ionic bond has a difference in electronegativities that is greater than 1.7, but not always.
What is the difference between covalent and ion bonds?
ionic bonds usually form salts and have an electronegativity difference of greater than 1.7. for instance NaCl (sodium chloride is an ionic bond) covalent bonds don't form salts (obviously) and they have an electronegativity difference that is less than 1.7 diatomic molecules such as nitrogen and oxygen (found in nature bonded as a pair) have an electronegativity difference of 0 which is a reason why they are covalently bonded with themselves
What type of bond has high electronegativity?
It depends on the difference in electronegativity between the two atoms. If the EN difference between two atoms is less than 0.5,the bond is nonpolar covalent. If the EN difference between the two atoms is between 0.5 and 1.6, the bond is polar covalent. If the EN difference between the atoms is greater than 2.0, the bond is ionic. If the EN difference is between 1.6 and 2.0, and if a metal is involved, then the bond is considered ionic. If only nonmetals are involved, the bond is considered polar covalent.
